The 2nd RDO is for a friend I ride with, My wife has had her RDO for a year.

I have had my Tang RDO for a year as well & I'm still impressed how well it goes.

Thanks....that's good to hear as I'm hoping to demo one as a racebike soon. I have an air9 and will either go hardtail RDO or the full suss option depending on how the latter pedals.
Sorry to mix up who the second bike was for!

Yes I can, the bike is a bit more point & shoot when riding along heavy cambered track were you must stay on line.

I notice this with the flows but if someone was using something like crests it wouldn't be as sharp.

Good point, rim selection and tire pressure make a difference with perception of flex. The 15QR feels a bit more solid in the rubble so I will go with 142x12 next time. Maybe the new jet 9c will eventually offer that as an option at a reasonable cost.

Well it the new Sir9 is 142x12 It can't be long before there are more Niners with 142x12 than without IMO

Ok I have just been for a 2 1/2 hour ride with my Jet9 RDO with full XX1 set up, But took the wheel with the XX1 cassette off & fitted the wheel with the 10 speed casette on it gave it a small tune & went out for my ride.

I have put a 30 tooth front ring on to give it a try on some of the very steep hilly trails I'm doing at the moment & its nice but don't feel I need it that low.

I'm still only doing ruff trails on the bike at the moment to get ready for some trips away over christmas & the XX1 has not missed a beat.

I will be selling all my 2x10 stuff & I have quite a bit of it but just can't see myself going back.

Old thread I know... Question to Muzz, you are selling your 2x10 stuff off. I've been considering 2x10 for my RDO build as I need the granny gear for steep climbs. My question is with XX1 do you miss not having that granny gear or is XX1 really that good? Seems they made it very versatile with the massive 11x42 cassette. Seems the idea is to make it to be all you ever need. What if your a semi strong rider, another words I'm not the strongest out there but can do ok. Considering the XX1 very strongly for my Jet 9 RDO build. Check this out:

I brought a 30 & 28 tooth ring for my XX1 when I brought the group set, I ran it on the 32 tooth ring that cam on the cranks for about a month & then thought I would give the 30 a go & have been ridding it since & haven't bothered trying the 28.

We are riding some very steep tracks were you have to fight to keep the front wheel down, I have a friend that has been riding for 5 months & is 207 lb & has not done any fitness before.

He has been riding one of my bikes & needed my 22/36 2x10 setup to ge the up the hills

He has just brought a cheap closeout Rip9, I have been lending him my group sets so he can try befor he buys,

He has run the 22/36 2x10 with 11-36 cassette for 2 weeks, On Monday I put XX1 on it & fitted the 28 tooth ring that I had, after the 1st run down the hill & back up he said order me that, That is really good.

I could have done him a good deal on my 2x10 setup but he opted to pay top dollar for the XX1 & had to spend another $300 more on wheels as well to do it.

28-42 is about the same as 22-36 in feel when riding, I hope this helps.

Thanks Muzz, yes that does help. Seems the XX1 with that massive cassette gearing will make a 2x unneeded. I guess its going to be XX1 for me.

One more thing Muzz, you have the SRAM XX1 "trigger shifters" correct? Are they like the Shimano XTR and XT trigger shifters that allow you to push till you double click and it skips gears really fast and does the same on the pulling?

Changing to a harder gear it will only go 1 gear per push but will change as quick as you can pull the trigger,

Going to an easyer gear it will go many gears at a time if you push the leaver far enough, However I only ever go a max of 2 gears at once because the clutch type deraileur does put more presser on the chain & I don't want to be to ruff on a cassette that costs that much.

As I see the Next SL 2x10 crankset complete with BB is 55g's lighter than XX1; however, the biggest benefit that I contemplate is not so much saving the 55g's but in the speed of change:

Someone said, and I couldn't have said it better, "Come to a bottom of a hill, fly around a corner: ‘Wow! Steep climb!’ Dump the front derailleur and you’re at least in the ball park (ready-quick-n-fast) for the climb."

Do you people who ride 1x systems not miss that? How about the few who are on the XX1 groupset, do you miss it? This is my concern.

Being that I am not the strongest of riders, my concern is shifting into the climb trying to get into that right gear while into the hill. I don't like shifting too much while in a climb, especially a steep one and putting a strain on this expensive groupo, then to have to get off and walk because I was not in the right gear.

Couple of things -
It may be lighter for the crank/bb but it won't be lighter overall once you add the left shifter and f. der.
When you drop to an easier chainring that takes what, maybe a second and a half to settle into the new rhythm? That doesn't happen when you move through a tightly spaced cogset. The last two huge cogs of XX1 might feel weird but it's way more fluid then dropping to a smaller chainring.

Shifting the front ring is approximately equivalent to 2 gears on the rear, and if you're down-shifting you can do it in one motion. Not to mention the rear shifts faster and you don't risk dropping your chain.
